ALBERT WARD PATTISON, OF LOCKPORT, NEW YORK.

vAronIvznn irYnnocAzaBoN-Bnmmn T o all whom t may oom-em.'

Be it known that I, ALBERT l WARD PATTI- soN, a citizen of the United States, residing at Lock ort, in thecounty of Niagara and State o. New York, have invented certain new and useful Improvements in Vaporizer Hydrocarbon-Burners, of which the following is a specification.

rllhis invention relates to burners of the type applicable to existing stoves, heaters, and the like, built to use solid fuel, such as coal, to convert them into stoves which can use liquid fuel, such as kerosene.

One object of the invention is to provide a burner of the character specified havingmeans for preventing formation and deposition of carbon upon the parts thereof.

Another object is to provide a burner having certain felicitous refinements of structure, going to make up the ultimate perfection of the burner in its entirety, as will appear hereinafter.

With these objects in view, the invention resides in the novel construction, combination and arrangement of parts, as will be fully hereinafter described in the specificatin, summed up in the claims, and illustrated in the drawings. v

The accompanying drawings clearl disclose an exemplary construction capa le of carrying out the underlying principles of the invention. Like reference characters denote corresponding parts throughout the several views, Briefly described:

Figure 1 is a view inside elevation of the burner of my invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a longitudinal sectional view on the llne 3 3, Fig. 2;

Fig. 4 is a transverse sectional view, on the'line 4-4, Fig. 2;

Fig. 5 is a top plan view of the base portion of the burner; and' Fig. 6 is a fragmentary view of a slight modification;

Fig. 7 is a longitudinal sectional View taken on a line corresponding to 3-'3, Fig. 2, of a modification; and

Fig. 8 is a sectional view, on line 8 8,

Yeferring, now, in detail to the drawings, and, first, to Figs. 1. to 5 thereof:

1 designates a base-plate adapted to rest upon the grate of the usual coal-or woodburnin stove, and may, as shown, be sub- Stantia ly retctangular in outline.`

i Specification-of Letters Patent.

Patented June 2s, 1921.

Application led May 25, 1920. Serial lilo. 384,189.

.The base-plate is provided with a plurality of preferably circular openings 2,` four being show n, one thereof being located at each corneryof the base-plate.

Surrounding each opening is a vertical,l

tubulariange 3, provided with an interior, ring-shaped ledge 4, constituting a support for a .spider-like dome-member 5 having a plurality of downwardly-curved, hollow legs or tubes 6 extending from a hollow central portlon 6 and resting, at their lower or free ends upon the ledges 4.

The central portion 6 has a bottom, annular opening 7 over the wall of which is spun the mouth portion 8 of an inverted truncated cone-shaped screen 9, the lower edge of which is inturned to form an annular iiange 10 supporting a hollow, preferably spheroidal body 11 numerously apertured, as shown at 12, for a purpose presently appeering.

Tapped into the top of said body 11 is a verticall disposed branch pipe 13, communicatlng, by a T-union 14, with a pipe15 leading from a suitable source of water supply (not shown).

Threaded into the T-union 14 and in aline ment with the pipe 13 is a vertical supporting rod 16, havlng a threaded upper portion 17 passing through the top of the central hollow portion 6 and carrying nuts 18, 18

bearing against the upper and under surface of said top of the member 6.

Disposed beneath and in vertical alinement with the spheroidal body "11 is a second hollow, preferably spheroidal body 19 supported by the upper, threaded end 20 of an oil-supply pipe 21 leadin from a suitable source of fuel-supply, pre erably an overhead tank or reservoir (not shown), said spheroidal body 19 being apertured, at its top, as shown at 22. Said spheroidal body 19 constitutes an oil-well. The base-plate 1 is provided with an upstanding annular bead 23 encircling and concentric with the spheroidal body 19, for a purpose presently appearing.

T e base-plate is furthermore provided with longitudinally-extending grooves 24, 24 upon the upper side or face thereof, which ygrooves are convergently inclined, so that they meet, as shown-at 25, and thence lea-d to an o ening 26 in the baseplate, at one end thereo into which an outlet-pipe is tapped. The-function of said grooves is to collect any overflow of oil escaping over the top of the to the outlet 26.

In operation, the device is applied to an existing stove, such as a lcook stove, by

`resting the base plate 1 upon the grate and then connecting the fuel-pipe 21 from an oil-tank to the base-plate. Fire-clay is then placed around the base-plate upon the grate, so that all the draft from the bottom of the stove, or ashpit, upwardly will be through the legs or tubes 6 of the spider-like dome.

Assuming, then, that the device has been installed, as above outlined, fuel oil is let into the feed-pipe 21, whence it will ow out into the Well 19, and thence through the opening 22 into the shallow tray 23. A match applied to the oil in said tray will set it on fire, which heats the spheroidal body 19, and thus vaporizes the incoming oil. F lame from the burning oil rises around the legs of the spider-like dome', and they become red-hot, so that air coming from the ash-pit into them through the openings 2 is heated to a high temperature. The air passes from the legs 6 into the hollow central member 6, and thence escapes through thebottom opening 7 thereof, whereupon it passes through the scieen 9 and mixes with the flame from the bui'ning oil, insuring the necessary combustion. The products of combustion passing between the legs and over the top of the spider-like dome effectively heat the stove in which the burner is installed. The iiue of the chiinney and the blast of the flame cause a continuous suction of air from the ash pit up through the legs of the spiderlike dome and out through the outlet 7 and thence through the screen 9 into the fiame.

In operation, also, water passin from the water-supply pipe 15 through he branch vpipe 13 into the spheroidal body 11, and thence through the openings l2, issues through the screen 9 in the form of steam, because of the higlily-lieated condition of said screen and body 11. This steam mixes with the air also passing throughl the screen, and with the vaporized oil issuing from the opening 22 of the spheroidal body 19, and prevents formation and deposition of carbon upon the parts of the burner.

Fig. 6 discloses a slight modification, in which, instead of the spheroidal body 11 of the device of the preceding figures, a substantially inverted cone-shaped hollow body 12 is used. With this exception, the parts of the burner of Fig. 6 are identical with those of the burner of the preceding figures.

Referring, now, in detail to Figs. 7 and 8:

The modied form of burner shown in these figures is adapted more particularly for use in burning crude or fuel oils. F or this purpose, it is desirable to introduce steam into the hollow body 19 (correspond ing to the element 19 of the devices of the preceding figures). To this end, a plurality of steam pipes 27 (herein shown'as four in number) communicate, by means of elbows 28 tapped into the hollow member 12', with said member, and, by means of elbows 29 tapped into the body 19, with said body, which latter is provided with the outlet orifice 22 for the oil fed to' said body by the pipe 21 tapped into the bottom thereof. A water-pipe 13 is tapped into the top of' the member l2.

In other respects, the structure shown in Figs. 7 and 8 is the same as that described in connection with the preceding figures of t-lie drawings, and, therefore, a description of such parts common to al] forms ot my invention will not beI repeated.

rlfhe operation of the burner ot' Figs. 7 and 8 Will be apparent: The water passing through the pipe 13 into the body 12 will be ithere converted into steam, and will passy through the pipes 27 into the oil-receptacle 19, where it is mixed with the heavy oil therein and passed out ofy the exit opening 22 when so mixed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is: j
